Compatibility
With the LS series, the controller and scanning head are calibrated as a
pair. To satisfy the specifications, therefore, be sure to combine a control-
ler and scanning head having the same serial number.
The transmitter and receiver are also calibrated as a pair.
When using 2 scanning heads, connect them respectively to the specified
connector port of the controller.
CHAPTER 7 Hints on Correct Use
Operating Environment
Be sure to operate the LS controller in a place where the temperature is
within a range between 0 and 45°C. (0 to 40°C for LS-3036/3060)
Fluctuation in ambient temperature may cause measurement error.
Always maintain the ambient temperature at a constant level. If the
ambient temperature changes by 10°C, it takes approx. 60 minutes for the
temperature distribution in the LS controller to become uniform.
Be sure to keep the laser emitting surface (transmitter) and the laser
receiving surface (receiver) free from any substance refracting light (such
as water or oil).
Blow off dirt or dust on the protective glass using clean air. If dirt or dust
still remains, wipe it off using a soft cloth moistened with alcohol.
The protective glass can be replaced. See the figure below to replace the
glass.
Countermeasures against
Noise
Do not mount the scanning head to the place where a certain level of
electrical noise is applied or transferred. Isolate the scanning head if
electrical noise may be occured. Otherwise, laser diode may deteriorate
or become damaged.
Keep the wiring or connection cable away from high-voltage lines or
power lines to prevent the LS controller from malfunctioning because of
noise.
Be sure to earth-ground the LS controller through the earth ground termi-
nal (No. 19). Insulating the scanning head is also effective in reducing
noise.
Fuse
When the fuse is blown, replace it with the following one:
Midget fuse: F-7142 2A or equivalent
Cooling Fan
Do not block the cooling fan on the back panel. Blocking it will overheat the
LS controller, causing malfunction.
